摘要
这里简述并图示了单极～偶极和对称四极装置测深原理及野外布极方式。根据单极～偶极装置视电阻率与施伦贝格尔装置视电阻率存在的内在关系,以及"等效电阻率法",给出了施伦贝格尔装置视极化率与单极～偶极装置视极化率的数学式,即时域激电单极～偶极装置测得的电性参数数据,可以转换为施伦贝格尔装置电性参数的数据,并对这两种测深装置视电阻率、视充电率分别进行二维反演、成图及对比,结合测区简单的地质特征,显示出两种装置测深具有相同的地质勘探效果。
This paper sketch and graphical show sounding principle and the electrodes array mode for pole-dipole array and symmetry four-pole(also Schlumberger) array.According 'the equivalent resistivity method',and the resistivity internal relation for pole-dipole with Schlumberger,we give equation for Schlumberger array chargeability with pole-dipole array chargeability.And we can also change pole-dipole array acquire electro-parameter data into Schlumberger array data,at the same time,we make two-dimension inversion,plot imaging and comparison for the two sounding array resistivity and chargeability parameter.At last,To combine simple geological character,shows same geological effect with the two type sounding array.
